Hi Marcus,
Try using the ViewState property on the page to save the CheckBox selection. Go through the following help article which explains more on this.
Persisting CheckBox control state in GridTemplateColumn on rebind
Thanks

Hi,
Can you post sample code for this issue with a simple RADDatagrid (without the master/detail).
I have tried with the code given in the link but it doesn't work. I don't think this is a version issue..
thanks and regards...

Seriously! I just need to persist a checkbox on a simple multipaged grid. The example code is way beyond what I need and it would take me hours to figure out how to adopt it. Why aren't checkboxes persisted by default? It seems to me that behavior is so obviously needed that it's incredible it's not built-in!
Cheers!

Hello Mark,
The controls placed in RadGrid templates (GridTemplateColumn in particular) can vary. Since they are not part of built-in grid elements there is no universal means to persist their state on grid rebind as opposed to a regular postback. That is why on explicit or implicit rebind operations (like paging) the controls in the templates are recreated as outlined in this topic but their state is not kept automatically. You can test the same behavior with regular MS GridView control to compare the result.
That is the reason why you need to track the state of the controls in grid templates with your custom logic and retain their previous test on rebind operations. I hope this explanation makes sense.
Kind regards,

Hey Sebastian,
Thanks for the reply, though not very satisfying. Almost all the online examples using checkboxes create ASP checkboxes in griditemtemplates. I actually started out with a gridcheckboxcolumn and couldn't get it to work in selecting its row for further processing and switched to the template option, which works great as long as you are not paging and needing persistence.
Oh well, I can write the code; I just prefer to be lazy.
Cheers!
